Sažetak
Seed quality is crucial for agricultural production. The basic indicators of seed quality are moisture, weight of 1000 seeds, purity, germination energy, germination and health. Germination energy and seed germination are tested according to a precisely prescribed methodology depending on the plant species. For each plant species, the substrate for germination is prescribed, the temperature in the process of germination, the number of days required to read the energy and germination of seeds, and pre-treatment if the seed has a pronounced dormant property. Germination testing temperatures are adjusted to optimal temperatures at the time of sowing a particular plant species, but in recent years due to climatic conditions it often happens that temperatures at the time when grain legumes are sown are significantly lower than the multi-year average. The aim of the research is to determine the influence of different temperatures on germination energy and germination of grain legume seeds. Testing of germination energy and germination of seeds of peas, fodder peas (spring and winter), grain beans (high and low), green beans (high and low), broad beans and soybeans was performed by the standard method in sand at three temperatures 15 °C, 20 °C and 25 °C. The prescribed germination testing temperature for all species is 25 °C, except for broad beans which is 20 °C. Research results show that seed germination at a temperature of 15 ° C is low in all tested species, except for spring peas and broad beans, while the germination energy of grain bean seeds, green beans and soybeans is 0%. The temperature of 20 °C had a negative effect on the germination energy and germination of seeds of grain beans, green beans and spring fodder peas, while in broad beans, winter fodder peas and soybeans the effect of temperature was positive on both seed quality indicators. Seeds of peas, grain beans and green beans had the highest germination energy and germination at a temperature o f 25 ° C. Low t temperatures a t t he time of germination can cause significant damage to grain legume crops because in most species the germination energy is 0% and the germination of seeds is very low.
